AnandTech: 64GB SSD on the Desktop: Samsung and OCZ go mainstream
new mainstream drives offering performance equal to the best mechanical desktop drives in most cases. The sustained read/write rates have increased to the 100/80 MB/s range. Capacities are now standardizing at 64GB with average pricing dropping to around $16 per-GB for the mainstream sector. The highest performing drives feature 120/120 MB/s read/write speeds with capacities up to 128GB, but pricing is around $29~$32 per-GB. In the high performance sector, we expect to see 150/100+ MB/s read/write performance shortly along with capacities up to 128GB around the current price range.
